Vim+latex+latex-live-preview underUbuntu

https://qaofficial.com/post/2019/04/20/68416-vim-latex-latex-live-preview-underubuntu.html 2019-04-20
When writing latex under windows, I found vim was really a good tool, so when switching to linux, I also wanted to integrate this set of tools. I actually use linux-mint, but it is based on Ubuntu, so I think it is similar. Main Steps:1. install vim, preferably vim supported by python. I will use apt-get to install it directly sudo apt-get install vim sudo apt-get install vim-gtkThis vim-gtk is vim with interface, namely gvim, which supports LATE-VIM-SUITE better.

What is your color value?-face scoring model based on tensorflow

https://qaofficial.com/post/2019/04/20/25420-what-is-your-color-value-face-scoring-model-based-on-tensorflow.html 2019-04-20
Preface Use neural network to evaluate the color value and score faces based on CNN.This project was published on GitHub a week ago. After that, I used the new public data set (the original project data set was not published), reset the network structure, and finally ran out of the model. I can get the code and trained model by accessing GitHub: HTTPS://GitHub.com/Roguesir/DL-Project/Tree/Master/FacesScore.

1, AVItoImage implementation In image processing, it is often necessary to convert video files into image file formats so that we can analyze images frame by frame and obtain useful information we need. The following programs realize the above functions, VC6.0 platform, and opencv1.0 library. #include "cv.h" #include "highgui.h" #include <stdio.h> #include <string.h> #include <iostream> using namespace std; char image_name[

pythonsysargv function

https://qaofficial.com/post/2019/04/20/68429-pythonsysargv-function.html 2019-04-20
sysargv is used to receive command line parameters, and a list is returned. usually, python test.py -h xxx -l xxx is required for running. py files. then sysargv obtains sysargv[0], sysargv[1], sysargv [ 2 ], where the value of sysargv [ 0 ] is " test.py", the value of sysargv [ 1 ] is " -h xxx", and so on. sysargv[1:] is actually a slicing operation, which means that the values after sysargv[1] are taken to form a new list.

Speaking ResNet is also the pride of our Chinese. It was proposed by 4 Chinese.He won the championship in ILSVRC 2015. words not much said, let's talk about my understanding, ResNet is very similar to Highway Network, which allows the original input information to be directly transmitted to the following layers.In the traditional neural network, there will be the problem of Degradation. As the accuracy rate rises to saturation, increasing

single classification

https://qaofficial.com/post/2019/04/20/68377-single-classification.html 2019-04-20
Single classification algorithms used in engineering practice include one-class svm and svdd, both of which have good effects, but one-class svm has slightly better effects than svdd, but svdd has fewer support vectors, which can achieve better real-time performance in practice. iforest is also another single classification algorithm, but it has not been tried yet. I don't know how the actual effect is, but it needs to be tried.

spring Startup Process-Principles of Spring and springMVC Parent-Child Containers

https://qaofficial.com/post/2019/04/20/68322-spring-startup-process-principles-of-spring-and-springmvc-parent-child-containers.html 2019-04-20
To understand the relationship between these three contexts, you need to be familiar with how spring is started in a web container.Spring's startup process is actually the startup process of its IoC container. For web programs, the startup process of IoC container is the process of establishing context. spring startup process: First of all, for a web application, it is deployed in a web container, which provides a global context environment.
